A vertical piston-cylinder assembly containing 0.3 Kg of steam, initially a vapor, is placed on a hot plate. Due to the weight of the piston and the surrounding atmospheric pressure, the pressure of the steam is 20 bar. Heating occurs slowly, and the steam expands at constant pressure until the final temperature is 200 °C. Show the initial and final states on T-v and p-v diagrams, and determine. (a) the volume occupied by the steam at each end state, in m3. (b) the work for the process.

A piston-cylinder assembly contains air at 210 kPa and occupies a volume of 0.01m'. The piston is attached to one end ofa spring and the other end of the spring is fixed to a wall. The force exerted by the spring on the piston is proportional to the decrease in the length of the spring. The ambient atmospheric pressure is 100 kPa. Now, the air in the cylinder is heated till the volume is doubled and at this instant it is found that the pressure of the air in the cylinder is 600 kPa.

Air is contained in a piston cylinder arrangement as shown in Fig.(Refer attachment). The piston can be assumed to be massless, frictionless, and perfectly insulated. 10 kg of dry ice (solid CO2) is placed on top of the piston. The initial conditions for air inside the cylinder are P1=121 kPa, T1= 300 K. Dry ice sublimates gradually, and its mass reduces to 5 kg. Ambient air is always at room temperature (27oC) and atmospheric pressure. (Given: R=287 J/kg ·K, g = 9.8 m/s2, CP/CV for air = 1.4; Neglect all heat transfer to the dry ice block.) a)Assuming the cylinder to be perfectly insulated, calculate the specific work done for the process. b)Assuming the cylinder to be perfectly conducting, what is the heat required per unit mass of air to complete the process? c) Plot the processes described in (a) and (b) together on a P-V diagram.
